Remove fix for old mysql bug; try to improve postgresql perf Supposedly mysql bug that causes test_mysql.mysqlDBTest.testFilteringSpecialChars to fail was fixed in 8.0.1 in 2017: https://bugs.mysql.com/bug.php?id=74901 Also disable fsync for postgres as we prefer speed to durability of data when running test suite. Need to find correct path for postgrsql.conf, so ls command added as well.

try:
    from html import escape as html_escape_  # python 3

    def html_escape(str, quote=False):
        # html_escape under python 3 sets quote to true by default
        # make it python 2 compatible
        return html_escape_(str, quote=quote)
except ImportError:
    # python 2 fallback
    from cgi import escape as html_escape  # noqa: F401
